hey all, am stuck here and need some help.
B650e phantom gaming ITX. updated to bios 1.24 when i got the board with no issues.
no bios flashback available, so i'm using instant flash. every time i select the bios to update, i get the 'updating' popup with the progress bar at 0% and then an immediate shutdown or reboot.
PC runs fine, no issues, but i want to move to a newer BIOS for some new larger capacity memory
i have:
- disabled AMD fTPM
- disabled any secure boot
- reset bios to defaults, which removed any memory/EXPO settings. memory and CPU at stock clocks
- removed GPU and all drives, re-seated memory, tried just 1 stick at a time
- reset CMOS - placed a jumper on the cmos reset, did not disconnect battery - i assume the battery is somewhere under the VRM heatsink and the manual doesnt mention disconnecting the battery at all...
- tried different usb sticks and usb ports
- tried updating to every single BIOS version (theres about 4-5 between my current one and the latest)
same results, instant 'click' and power-off or reboot at the 0% progress bar.
thanks in advance for any ideas
